Cabin Air Filters

Studies show that the air quality inside cars on most roads is even worse than the outside air. That's because the heating, air conditioning and vent system has the effect of concentrating contaminants inside the passenger cabin when it draws in outside air and the windows are closed.

Kleener® cabin air filters do for the passenger compartment of your car what heating & air conditioning filters do for your home - they filter and clean the air before you breathe removing dust and allergens.

Like other filters on your car, cabin air filters need to be changed at routine intervals. We recommend every 18,000 miles. Refer to your owner's manual for the recommended filter changing procedure or see a professional mechanic.

  • Why do people need Kleener® cabin air filters?
    Think of them as an air filter that cleans air before it enters the passenger compartment through the heating, air conditioning or fresh air systems. The new filters remove allergens and pollutants before they get into the car and before they can be inhaled by the driver and passengers. Roadside air contains significant numbers of contaminants such as pollen, dust, diesel soot, and smog, and the contaminants can be more concentrated inside a car than outside.
  • Does the filter help allergy sufferers?
    Yes. The filter reduces the concentration of all pollen and dust particles that may cause allergic reactions. Such particles are generally 1 to 100 microns in diameter. A dot made with a sharp pencil is huge at 200 microns.
  • Do Kleener® cabin air filters keep car interiors cleaner?
    The new filters greatly reduce the amount of dust and pollutants entering the car, so inside glass, dashboards, heating, ventilating and air conditioning systems do tend to stay cleaner.
  • How does the filter work?
    Filter fibers are of specific sizes, allowing the filter to work at high efficiency because it holds contaminants within the media. This reduces the chance of surface clogging and allows the filter to last longer.
  • How effective are Kleener® cabin air filters?
    These filters are extremely effective. They remove a significant allergen concentration from outside air.
  • What size particles do Kleener® cabin air filters trap?
    The filter traps particles to 1 micron in diameter and larger. A human hair is between 80 and 100 microns in diameter, so many of these particles are invisible to the naked eye.
  • What is the filter's change interval?
    Like any other filter, Kleener® cabin air filters need to be changed at routine intervals, following the vehicle manufacturer's recommendation, or click on the "+ View Application and Installation Information" link above.
  • What happens if the filter is not changed?
    Air will still flow into the passenger cabin through the heating, air conditioning and fresh air systems. Once the filter media is saturated with contaminants, however, the pollutants and allergens may start entering the passenger cabin as well.
